View/edit a column - North China and E. Yunnan epoch (Cambrian)

TimeScaleCreator displays data in columns, as selected in the Choose Columns pane of TSC settings. This page allows selection of a column and review of metadata on it. It also displays the content of the column.

Columns which have not yet had data imported into this database are not shown.
Column colour is based on the dataset/subdataset so the options to change colour are given on the dataset page.
Most col names have been copied from TSC, to activate an existing column enter the dataset_id directly in the arkL_columns database
Once columns exist and are assigned to a datset they can be edited from this page
Events and intervals are not directly assigned to a column in the database instead the column metadata defines which events and intervals are selected

Column mock-up

This column mock-up plot is a simple plot of the data to allow visual comparaison with the output from TimeScale Creator. For interval tables the defining events are also shown

The data plotted here is the North China and E. Yunnan epoch (Cambrian) column from the stages North China (Camb) dataset for the interval. For intervals tables the events re also shown 0 - 700 Ma
